Biography

I received my Ph.D. in Computer Science and Engineering from University of California Santa Cruz under Prof. Chen Qian, and I got my Bachelor's degree from University of Science and Technology of China. In the past, my research interests are in systems, including RDMA-based disaggregated databases, vector db, and AI infrastructures.
